Subject: linux-next: build warning after merge of the net-next tree

Hi all,

After merging the net-next tree, today's linux-next build (powerpc
allyesconfig) produced this warning:

In file included from drivers/net/ethernet/ibm/ibmvnic.c:52:0:
drivers/net/ethernet/ibm/ibmvnic.c: In function 'ibmvnic_open':
include/linux/dma-mapping.h:571:2: warning: 'dma_addr' may be used uninitialized in this function [-Wmaybe-uninitialized]
  debug_dma_mapping_error(dev, dma_addr);
  ^
drivers/net/ethernet/ibm/ibmvnic.c:852:13: note: 'dma_addr' was declared here
  dma_addr_t dma_addr;
             ^

Introduced by commit

  4e6759be28e4 ("ibmvnic: Feature implementation of Vital Product Data (VPD) for the ibmvnic driver")
